DH and I did the formal Hyponobirthing class series (8 weeks) with my first pregnancy. Unfortunately, despite trying acupuncture, the Webster Technique, homeopathy, flower essences, inversion exercises and a very painful external version, DS was in a complete breech position and was born via C-section, so I was never able to actually try the techniques. I do, however, have friends who took the Hyponobirthing classes and had natural births, and everyone has told me that they were a bit surprised (and irked!) to find out that they actually had to do a lot of pushing to get the baby out; it wasn't as simple as just "breathing the baby down" as the Hyponobirthing technique implies. I'm sure that there are lots of mamas out there who have had great experiences with Hypnobirthing--these are just the expereinces of a few women I know. I do think that the relaxation and visualization aspects of Hyponobirthing are wonderful and very helpful, whether the "breathing down" is enough by itself or not.
